Crawling while print a straight line

[eng-ihab]

Hello,

I've HP DesignJet T795  44-Inch have a problem while printing a straight line or any scheme,

Please see the below photo for more details,

See the original file that i want to print.

and the result was like this,

It will be like a zig-zag line not straight line like the original,

I've tryied to clean everything inside the printer, i did many calibration and printhead alignment and upgrading the firmware, i get access to the service menu and i test each part and component and module and carriage assembly, also the IDS and service station, all pass without issue, also i tried to change the paper media and size, still the same thing.

Is there any one have experience on this issue so he can help me with this matter

Thanks in advance

Best Regards,

Hi,

In crease the print quality to Normal or Best. That will fix it

If you still want to print your files using Fast mode, try the following

- Do the EERom reset

- Clean the encoder strip

- Do the scan axis calibration (use the proper paper)

- Do the paper advance calibration

- Do the printhead alingment

Now BEFORE THAT.

- Make sure the paper is loaded correctly

- Make sure all the printheads are firing correctly

- Make sure the paper selected on the front panel match the paper you are loading. ie. Dont load Bright white inkjet bond, bond or coated paper as PLAIN, they are not the same.

Hi,

Thank you for your replay,

The printer is already in normal quality, also i have 3 printer same model same settings and they working normaly without crawling, I try to use best quality the line was good without any crawling, but in other printers its in normal quality but they don't have crawling while printing a straight line

You said Do the scan axis calibration (use the proper paper), what do you mean by proper paper ??

Is there a special paper for scan axis calibration ?

Thank you
